CONTAINER.

Application flled September 23, 1925. Serial No. 58,068.

This invention relates to containers of the class known as collapsibletubes, and more particularly to a cap for said container and means forsecuring said cap to said container.

The object of the invention'is to provide a container having a cappermanently attached thereto, said cap being so constructed and attachedto the neck portion of the container that it may be quickly and easilymoved into a closed or open position without danger of becomingaccidentally detached from said container and lost.

The container of this inventionis an improvement over a containerillustrated in a previous patentgranted to me, namel No.

1,4et1,705, dated J anuary'9, 1923, and is provided for the purpose ofincreasing the efli ciency and tightening action of the cap,particularly when the device is constructed of soft metal as isgenerally the case.

The invention consists in the combination and arrangement of parts setforth in the following specification and particularly as pointed out inthe claims thereof.

Referring to the drawings Figure 1 represents a front elevation of theupper portion of a container embodying Fig. 2 is an elevation as viewedfrom the ri ht of Fig. 1.

the line 3-3 of Fig. 1. i

Fig. 4: is an elevation similar to Fig. 2 illustrating a ,cap in its upermost position.

Fig. 5 is an elevation similar to Fig. 4 illustrating the cap tipped toa position to allow the contents'of the container to be removedtherefrom. 1

Fig. 6 is a plan view of Fig. 5.

Like numerals refer to like parts throughout the several views of thedrawin s.

In the drawings, 1 represents t e main body portion of the container,preferably a collapsible tube formed of soft metal,' although it shouldbe understood that my invention is capable of being embodied in othertypes of containers where a suitable neck portion is provided. The'conta1ner 1 is provided with a cylindrical neck port1on 2 havinggrooves 3 upon opposite sides thereof, a portion 4 of said groovesextending longitudinally of said neck portion 2 and each of said groovesterminating at their lower ends ina helical portion 5 which extends fora portion of the distance around the circumference of said neck. Theupper Fig. 3 is a longitudinal section taken on end of the longitudinalportion 4 of each portion 2, connecting with the interior of thecontainer 1, said cap 6 being provided for the purpose of closing saidpassage.

The cap 6 is constructed of soft metal well I known to those skilled inthe art and is adapted to closely fit the neck portion 2 of thecontainer. The cap 6 is provided with two ears 8 on opposite sidesthereof, said ears each having a projection 9 formed integral therewithand adapted to project into the grooves 3. It is evident that in placeof forming the projections 9 integral with the ears 8 that pins may beprovided secured to said ears without departing from the spirit of thisinvention. The lower edgev of the cap 6 is out awayat 10 so that whenthe projections 9 are located at the upper extremities of, thelongitudinal portions 4. of the grooves 3 that said cap mav pivot at theupper ends of said" grooves an be swung to the position illustrated inFigs. 5 and 6, at which time the passage 7 through the neck portion ofthe container is entirely open and the'contents of the container may .beremoved' therefrom in the usual well known manner without danger of saidcap interfering with the removal. of said contents from said container,or without said cap becoming disengaged from said contamer.

That portion of the container hereinbefore described is old in the art,having been disclosed in the lpatent hereinbefore mentioned. To increaset e efliciency and holding power of the cap 6 in order that the lattermay more tightly engage the upper extremity of the neck portion of thecontainer when the passage 7 through the neck portion thereof is closedtwo other grooves 11 are provided upon opposite sides of said neckportion. A,

formed integral with the body portion of the cap 6 to easily enter said'ooves. The lonbetween the projections 9 upon the cap 6.

In closing the container, the cap 6 is moved to the osition illustratedin Fig. 4 and then pushe downwardly until the ro'ections 9 and 14 reachthe bottoms of t e longitudinal portions 4 and 12 of the grooves 3 and11 respectively and said cap is then rotated, whereupon the projections9 and 14 will engage the upper edges of the helical portions 5 and 13 0said ooves, thereby forcing the under surface 0 the cap 6 tightly aainst the top extremity of the neck 2 of sai container, as illustratedin Figs. 1, 2 and 3, thereby tightly closing the passage 7.

The cap 6 is at all times attached to the neck portion 2 of thecontainer 1 and said cap may be opened and closed as desired withoutdanger of becoming separated from said container and becoming lost. Inmoving the cap 6 to its closed position, the projections 14 and grooves11 co-operate with the projections 9 and grooves 3 in causing said capto tightly engage the upper extremity of the neck 2 and thereby closethe passage 7.

I claim 1. A container having, in combination, a neck portionprovided'with grooves formed upon the opposite sides thereof and closedat their upper ends, said grooves each comprisin a portion extendinglongitudinally of sai neck portion and a helical portion extendingcircumferentially around said neck portion, said neck portion alsohaving other helical grooves opening to the upper extremity thereof, anda cap slidably mounted upon said neck'portion and embodying therein earsvhaving projections thereon adapted to engage the helical portions ofsai' first-mentioned grooves, sa1dcap also having other projectionsthereon adapted to engage said second-mentioned grooves, all of saidprojections oo-operating with the helical portions of their respectivegrooves to force said .cap against the upper extremity of said neckportion,vsaid first-mentioned projections also constituting pivots forsaid cap when "said projections are located at the upper ends of thelongitudinalportions of their respective grooves.

2. Acontainer'having, in combination, a neck portion provided with twopair oi. oppositely dis osed grooves formed therein, each of saidgrooves comprisin a portion extending longitudinally of said neckportion and a helical portion extending circumferentially around saidneck portion, one pair of said grooves being closed at their upper endsand the other pair of said grooves belng open at their upper ends andintersecting the upper extremity of said neck portion, and a capslidably mounted upon said neck portion and embodying therein earshaving projections thereon adapted to en gage the helical portions ofsaid closed en ed grooves whereby said cap may be forced against theupper extremity of said neck portion, said projectionsalso constitutingpivots for said ca when located at the upper extremities oi theirrespective grooves, said cap also having other projections formedthereon adapted to enter said open ended grooves and engage the helicalIportions thereof and co-operate with said rst-mentioned projections inclamping said -cap against the extremity of said neck portion.
